* pango/opentype/Makefile.am: Don't include harfbuzz-dump.[ch] in
libharfbuzz.a. Those are just used by the harfbuzz-dump tool.

* pango/opentype/harfbuzz-buffer.[ch]: Rename buffer->inplace to
buffer->separate_out with the inverted meaning, such that buffer
is initialization is memset(0).

Bug 485621 – Get rid of freetype memory allocator in harfbuzz

Bug 485559 – Boston Summit HarfBuzz optimizations
* pango/opentype/*: HarfBuzz hacking to:
- Rename last remaining FT_Err stuff to HB_Err.
- Fix a couple invalid table paths to be permissive so
fonts work better. Particularly GDEF table for Nafees
Nastaliq is loaded and works great now.
- Optimize harfbuzz buffer to not copy/swap for simple
one-to-one and "copy" GSUB operations.
* pango/pango-ot*: Update to FT_Err to HB_Err renaming.
